7754380 ÷ 780 
We want to divide 7754380 by 780.

Let's proceed to step 1:
When dividing 7 by 780, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 780

Step 2:
When dividing 77 by 780, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 780

Let's proceed to step 3:
When dividing 775 by 780, we get 0 with a remainder of 775.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 775, we get 775.
Take the next digit (4) from the dividend and append it to 775, then repeat: 7754 / 780

Going ahead to step 4:
When dividing 7754 by 780, we get 9 with a remainder of 734.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7020 from 7754, we get 734.
Grab the next digit (3) from the dividend, add it to 734, then carry on: 7343 / 780

Moving on to step 5:
780 can be fit into 7343 9 times, resulting in a remainder of 323.
The next digit of our result is 9. 
Result so far: 99.0
If we take 7020 away from 7343, we end up with 323.
Fetch the next digit (8) from the dividend, attach it to 323 and continue: 3238 / 780

Advancing to step 6:
3238 divided by 780 is 4 with a remainder of 118.
Put 4 as the next digit of the answer. 
Result so far: 994.0
If we subtract 3120 from 3238, we get 118.
Include the next digit (0) from the dividend after 118, then repeat: 1180 / 780

On to step 7:
The number 780 fits into 1180 1 times, leaving a remainder of 400.
Write down 1 as next digit of the result. 
Result so far: 9941.0
Subtract 780 from 1180 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 8:
The number 780 fits into 4000 5 times, leaving a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 9941.5
The remainder is 100 after subtracting 3900 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 9:
When dividing 1000 by 780, we get 1 with a remainder of 220.
Use 1 as the next digit of our solution. 
Result so far: 9941.51
Deduct 780 from 1000 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 10:
2200 divided by 780 is 2 with a remainder of 640.
The next digit of our result is 2. 
Result so far: 9941.512
Subtracting 1560 from 2200 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 11:
If we divide 6400 by 780, we get 8 and a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 9941.5128
Subtract 6240 from 6400 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
1600 divided by 780 is 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 9941.51282
The remainder is 40 after subtracting 1560 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
400 divided by 780 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 9941.51282
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 14:
The number 780 fits into 4000 5 times, leaving a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 9941.5128205
The remainder is 100 after subtracting 3900 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 15:
780 goes into 1000 1 times with a remainder of 220.
Write down 1 as next digit of the result. 
Result so far: 9941.51282051
Deduct 780 from 1000 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final result is 9941.51282051 with a remainder of 2.2e-07.
